[LaAdriana]

Honda Civic key fob battery replacement steps are as follows: 1. First, remove the mechanical key from the Honda Civic key fob by using the metal key to pry open the key slot. 2. Locate the battery position, then replace the old battery with a new one, ensuring the positive side faces upwards, and reinstall it. 3. On the front side of the Honda Civic key fob, there is a small switch; manually press it and pull the top silver part to remove the mechanical key. 4. After removing the key, you will notice a groove at the top. Use the mechanical key to leverage and pry open the key fob by applying force upwards and downwards. At this point, the key fob splits into three parts, clearly revealing the battery position. Remove the old battery and install the new one, making sure the positive side is facing upwards, then reattach the cover to complete the replacement.
